Rhythm: Irregular with an oscillating or spindle looking twist around the baseline P Waves: Absent, yet if by chance you see some, they will not be related to the QRS complexes P-R Interval: Chaotic QRS Complex: Each differs from its neighbor. There will be an overall effect of tall QRSs...
Irritated ventricular foci that's SUDDEN, 150-250 BPM, large consecutive PVC complexes Paroxysmal ventricular tachycardia (AKA V-TACH) Ventricular tachycardia is associated with? Fusion/Capture beats Capture beat Normal ventricular depolarization VIA the atria with normal QRS complex- normal beat in the...
What is a PVC occurring between 2 normally conducted QRS complexes w/o interfering w/ the normal cardiac cycle and no compensation pause? Interpolated Ventricular Beat What is UniFocal? Firing from the same spot Whats a common Flutter Rate?
of atrial complexes from a single rapid-firing atrial focus. Many flutter waves needed to produce a ventricular response. (pages 159, 160) Ventricular Flutter (pages 161, 162) also see “Torsades de Pointes” (pages 158, 345) A rapid series of smooth sine waves from a ...

-regular P waves and regular QRS complexes; however, they have no relationship to each other and "march out" separately-usually results in decreased CO, ischemia, HF, and shock-can lead to syncope third degree AV heart block treatment -pacemaker-drugs to increase HR if needed while awaiting ...
premature ventricular complexes PVCs that come from a single focus; all look alike unifocal PVCs PVCs from different foci look different Multifocal PVCs have an upwards deflection left ventricular PVCs have a downwards deflection right ventricular PVCs ...

EKG shows a regularly tachycardia at 150 bpm with narrow QRS complexes (you know its supraventricular in origin). The P waves are inverted in leads II, III, and avF indicate abnormal (ectopic) atrial activity Which of the following is the best interpretation of this EKG?
